* * * * * /bin/bash -l -c 'cd /Users/boris/projects/MyApp/ && rails runner "Resque.enqueue(Place)"'

Basically I need to do the following:

  1. Load Ruby with RVM
  2. Navigate to MyApp Dir
  3. Run the following line: rails runner "Resque.enqueue(Place)

The above cron seems to be running, but its producing the following errors with rails runner whats going on?

Actually the best way to do this is to use rvm wrapper. You can create a wrapper like this: 

rvm wrapper ruby-1.9.3-p0@somegemset appname rails

binary can be rails, rake, gem or whatever other ruby binary you have installed. What happens is that rvm creates a wrapper that will source the correct rvm environment before executing the rails command. On system wide rvm, the wrapper will normally be placed in /usr/local/rvm/bin/

Now from cron you can just do: 

*/3 * * * * cd /path/to/your/app && appname_rails runner "Resque.enqueue(Place)" -e production

This will cd into your app directory and execute the rvm wrapper you just created every 3 minutes. This example is based on rails 3 and production environment.

You need to source the right environment via RVM before any Ruby code runs. So include something like this in the command:

source /usr/local/rvm/environments/ruby-1.9.2-p180@my-gemset

So a potential solution would be:

SHELL=/bin/bash
* * * * * source /{path_to_rvm_environment_for_ruby}@{gemset} && cd /Users/boris/projects/MyApp/ && rails runner "Resque.enqueue(Place)"'

Lots of moving pieces here, here are a couple of pointers on things to check in your environment (ruby, rvm, bundle) - post your findings and will go from there.

Path's issue with bundler, to change or not to change?

Bundle bug

I guess the commands runs fine outside of cron? if you're running your cron job as a different user, check the environment of that user.
